Negotiation and Problem Solving

A father left 17 camels as an asset for his three sons.

When the father passed away, his sons opened up the will.


The Will of the father stated that the eldest son should get half of 17 camels while the middle son should be given 1/3rd (one-third). The youngest son should be given 1/9th (one-ninth) of the 17 camels.
As it is not possible to divide 17 into half or 17 by 3 or 17 by 9, three sons started to fight with each other. So, the three sons decided to go to a wise man.
The wise man listened patiently about the Will.
The wise man, after giving this thought, brought one camel of his own and added the same to 17. That increased the total to 18 camels.
Now, he started reading the deceased father’s will.
Half of 18 = 9. So he gave the eldest son 9 camels
1/3rd of 18 = 6. So he gave the middle son 6 camels
1/9th of 18 = 2. So he gave the youngest son 2 camels.
Now add this up: 9 plus 6 plus 2 is 17 and this leaves one camel, which the wise man took back.
Have a nice day!

Moral :The attitude of negotiation and problem solving is to find the 18th camel i.e. the common ground. Once a person is able to find the 18th ground the issue is resolved. It is difficult at times. However, to reach a solution, the first step is to believe that there is a solution. If we think that there is no solution, we won’t be able to reach any!

Our reaction to the Problems

Really nice story- Cockroach theory!! 

At a restaurant, a cockroach suddenly flew from somewhere and sat on

a lady. She started screaming out of fear. With a panic stricken

face and trembling voice, she started jumping, with both her hands

desperately trying to get rid of the cockroach.

Her reaction was contagious, as everyone in her group also got

panicky.

The lady finally managed to push the cockroach away but ...it landed

on another lady in the group.

Now, it was the turn of the other lady in the group to continue the

drama.

The waiter rushed forward to their rescue.

In the relay of throwing, the cockroach next fell upon the waiter.

The waiter stood firm, composed himself and observed the behavior of

the cockroach on his shirt.

When he was confident enough, he grabbed it with his fingers and

threw it out of the restaurant.

Sipping my coffee and watching the amusement, the antenna of my mind

picked up a few thoughts and started wondering, was the cockroach

responsible for their histrionic behavior?

If so, then why was the waiter not disturbed?

He handled it near to perfection, without any chaos.

It is not the cockroach, but the inability of the ladies to handle

the disturbance caused by the cockroach that disturbed the ladies.

I realized that, it is not the shouting of my father or my boss or

my wife that disturbs me, but it's my inability to handle the

disturbances caused by their shouting that disturbs me.

It's not the traffic jams on the road that disturbs me, but my

inability to handle the disturbance caused by the traffic jam that

disturbs me.

More than the problem, it's my reaction to the problem that creates

chaos in my life.

Lessons learnt from the story:

I understood, I should not react in life.

I should always respond.

The women reacted, whereas the waiter responded.

Reactions are always instinctive whereas responses are always well

thought of, just and right to save a situation from going out of

hands, to avoid cracks in relationship, to avoid taking decisions in

anger, anxiety, stress or hurry.

Have a nice day.

OpenERP 7.0 : Gain/Loss Exchange Rate Account

What is Gain and Loss Exchange Rate Account ? How We can use and configure it in OpenERP ?

To enable it, First install account_voucher module.

Go to the Settings --> Configuration --> Invoicing and In Features option, Tick 'Allow Multi Currencies'.

As soon as you will tick it, You will see 2 more account fields which are Gain Exchange Rate Account and Loss Exchange Rate Account.

Gain Exchange Rate Account should have Regular as Internal Type and Income as Account Type.

Loss Exchange Rate Account should have Regular as Internal Type and Expense as Account Type.

Scenario 1:

Suppose INR is base currency and USD has rate 50.00 in respect of INR.
I create an invoice of 1000 USD and validate it. Now before payment, I change rate of USD from 50.00 to 40.00.
After setting a new rate, I make a payment of it. After payment, I can see that Gain Exchange Rate Account will be credit with 5.00 amount.
1000/50 = 20 and 1000/40 = 25 means 25-20 = 5

Scenario 2:

Suppose INR is base currency and USD has rate 50.00 in respect of INR.
I create an invoice of 1000 USD and validate it. Now before payment, I change rate of USD from 50.00 to 60.00.
After setting a new rate, I make a payment of it. After payment, I can see that Loss Exchange Rate Account will be debit with 3.33 amount.
1000/50 = 20 and 1000/60 = 16.67 means 20-16.67 = 3.33

It means that Gain / Loss Exchange Rate Account will be updated on the base of Residual Amount.
If Residual Amount is > 0, OpenERP will consider Loss Exchange Rate Account for debit.
If Residual Amount is < 0, OpenERP will consider Gain Exchange Rate Account for credit.

Hope this post will help you, guys. See you later.

OpenERP 7.0 : Attributes _track and track_visibility

_track on the object is used to track events related to a document (an invoice has been paid, an opportunity is won, a task is blocked, ...). Users can follow events, represented by a mail.message.subtype, on any object.

It's different from the track_visibility attribute that you can define on a field which is used to track changes on this field. (e.g. Stage: Proposition --> Negotiation)

Both _track and track_visibility produces messages on the document. Your object need to inherit from mail.thread.

If an object is inherited from 'mail.thread' then _track is used to send notifications. Therefore 'module.subtype_xml' is the related  "Message Subtype". These subtypes have to be declared in XML. Here is an example:

<record id="subtype_xml" model="mail.message.subtype">

    <field name="name">Relevant Fields</field> 

    <field name="res_model">project.issue</field>

    <field name="default" eval="True"/>

    <field name="description">The issue has been closed.</field>

</record>

Then whenever the field "field" is updated, all subtypes ("subtype_xml", "subtype_xml2") of this field are processed.

This means that the related method (in this example: lambda ...) is called and if the result is True, then for all users which follow this object and have checked the subtype a notification is created.

In the user preferences every user can choose whether he/she wants to be updated by email in case of new notifications.

You can also set a mail.message.subtype that depends on an other to act through a relation field. Here is an example from crm for Sales Teams crm.case.section using the section_id m2o in crm.lead: 

<record id="mt_lead_won" model="mail.message.subtype">

    <field name="name">Opportunity Won</field>

    <field name="res_model">crm.lead</field>

    <field name="default" eval="False"/>

    <field name="description">Opportunity Won</field>

</record>

<record id="mt_salesteam_lead_won" model="mail.message.subtype">

    <field name="name">Opportunity Won</field>

    <field name="res_model">crm.case.section</field>

    <field name="parent_id" eval="ref('mt_lead_won')"/>

    <field name="relation_field">section_id</field>

</record>

This allows a user to follow all "Opportunities Won" that are in a specific sales team. The user follow the event "Opportunity Won" on a sales team and he will become automatically follower of all leads/opportunities of this sales team and _track event.

Hope this post will help you to understand the concept of _track and track_visibility.

Operational Error coming during starting of OpenERP Server

Hi all,

Yesterday, when I tried to start my openerp-server, I got an traceback as below:

Operational Error: Could not connect to server: No such file or directory

Is the server running locally and accepting

Connections on Unix domain socket "/var/run/postgresql/ .s.PGSQL.5432"?

Error says that There was no postgresql service running on my machine.

So I opened my terminal and fire this command:

ps aux | grep post

but I did not find any result.

After that, I fired this command to start postgresql service:

sudo /etc/init.d/postgresql start

After firing this command, I found this error:

* The PostgreSQL server failed to start. Please check the log output.

After that, I went to the /var/log/postgresql/..LOG_FILES, I did not find anything over there.

It seems that it was an bad permission issue. I needed to create a new group that includes only postgres users with all necessary rights like this:

sudo groupadd dbtest

sudo usermod -a -G dbtest postgres

sudo chgrp -R dbtest /var/log

sudo chmod -R 770 /var/log

After this, I again started postgres service by firing the same command:

sudo /etc/init.d/postgresql start

And, finally I was able to see the log that was coming during that.

It was as below:

FATAL: data directory "/var/lib/postgresql/9.1/main" has group or world access

DETAIL: Permissions should be u=rwx (0700).

It was a wrong permission issue and I fired this command to solve that:

sudo chmod -R 700 /var/lib/postgresql/9.1/main/

After this, it works fine. I was able to start and stop postgres service as normal. As this issue been solved, I was able to start OpenERP Server successfully.

To solve this, I spent much time on this and that's why, I am posting this in my blog, so one does not need to try and spend much time for this if google shows my blog link to him/her regarding searching of this issue :-)

Hope this will help you.

See you later.
