Relation between Task List Group , Group counter and Planning Plant

Former Member

Hi SAP Gurus ,

Sorry for writing a long question

I am trying to understand the relationship between General task list Group , Group counter and Planning Plant

Planning Plant

General Task List

Group

Group Counter

1000

A

100

01

2000

A

100

02

3000

A

100

03

Question 1 :

If I create a General task list wrt planning plant 1000 (mandatory field) with group=100 . SAP creates the group counter as 01 .

For planning plant (2000) when I copy and create the same General task list of but with dirffrent planning plant (2000) with group =100 , system creates group counter as 02 (and does allow not extend this to group counter 01)

Why doesn’t SAP allow me to create a same General task list  with same Group (100) and Group counter (01) for different Planning plants .

Planning Plant

General Task List

Group

Group Counter

Remark

1000

A

100

01

2000

A

100

01

Results in error as Counter number already exist

. I assume SAP considers the same general task list if created for different planning plants as different task list and hence assigns a different Group counter .Is my understanding correct ?

Question 2 :

If a general task list (A) with Group(100) , Group counter (01) and planning plant (1000) is assigned to Maintenance plan (555) for equipment (Pump) for Plant 1000

Later this equipment was moved to another plant (2000) , so we removed the existing group(100) , group counter (01) and changed / created a new general task list (A) with Group(100) , Group counter (02) and planning plant (2000) and assigned this to maintenance Plan (555)

Again after 3 months if the equipment now needs to be sent back to Plant (1000) ,

Can I  reassign general task list (A) with Group(100) , Group counter (01) and planning plant (1000) that was created earlier to Maintenance plan (555) for equipment (Pump) for Plant 1000. Is this a good way of changing task list (Instead of creating a new task list every time the eqipment moves)

Planning Plant

General Task List

Group

Group Counter

1000

A

100

01

1100

A

100

02

This would  help me to create task list for various plants and reuse tasklist  when ever equipment moves from one plant to another .

Frazer,

This must be the best presented question I've seen on this forum..

Question 1:

The unique table-key for a general task list includes the task list type, group and group counter (see TCode SE11). It does not include the plant - this is just a mandatory field.

And as you have already determined, a group can contain multiple counters from different plants.

Question 2 :

If the equipment keep moving plants, then you could certainly contract your task lists as described above.

Hi Peter ,

Thanks for reading my question and replying . As I had written a long essay .

Question 1:

If the unique table-key for a general task list includes the task list type, group and group counter .

They why SAP does not allow us create single task list  with same Group and Group counter and allow us extend it to various Planning plants ( Just the way we extend our materail masters to various plants)

Though I understand that it is possible via development or by activating other module functionality provided by SAP  as mentioned in the link provided by you .

Once again thank very much . You are a Champ.

The "key" of a table means that there can only ever be one entry in that table with the same values i.e. you cannot have duplicates..

So table PLKO can only have one entry as follows A-TLGRP-01

The development options allow you to manipulate task lists data, not create duplicated values in the tables.

Greetings Frazer,

As Peter explained, the Plant is not part of the Task List key. So you can only create a Task list with a given composite key of Group and Counter for one Planning Plant.

If you want to be abvle to select similar plans for different Plants easily, I suggest you either

a) Create Task List Coutners within the group for separate plants, e.g. in group 1 create counters 10 (plant 1000), 11 (plant 1100) etc.

or

b) Create Task List groups in such a way that one group only has plans for the same Planning Plant.

This will help you assign the right task list to the Maitnenance Plan or Order when needed.
