Account assignment category in PO

[Former Member]

In the ECC5.0 release,I can't change the Account Assignment Category in a service position, if I derive the Purchase Order from a Purchase Requisition.

I.E.: I create a PR for service whit K Account Category for all sublines, the PO I created by this PR, don't allow me to change Account Assignment Category.

The problem there isn't for materials.

There is a solution for this matter?

Ciao Fabio,

Please, kindly check the information contained under the SAP note:

366850 ME21N ME51N Service accnt assignmnt ready for input

360632 - ME21N Various improvements for account assignments.

As stated in it:

"Ad point 6)

It is now possible to change the account assignment category from

'Unknown' to something else. Not however from (for example) 'cost

center' to something else. This restriction only applies to service and

limit items. The field selection must also be set as a prerequisite as

described in Note 313120".

What these notes have done is to make this process an EXPLICIT one; by

making the Account Assignment TAB not changeable when services or limits

are involved. Before, the Acct Assgmt TAB was open for entry, which

confused users in thinking that they could maintain the data there,

wherin reality, they couldn't (and they thought it was a bug and logged

many problems with us).

Hope this information helps you.

Ciao David,

Thanks for your help.

I verified the two notes you indicated in your message was applied in ECC5.0 and it is so, but I can't change AAC in Purchase Order also from 'U' to something else.

Do you know why?

Ciao Fabio,

If you set AAC "U" in the Purchase Order, you can enter a

new AAC when you enter the service entry sheet.

Can you please try this?

Hi David,

I solved the problem following the OSS note:

313120 - ME21N:Accnt assgmt cat fr item cat D cannt be chngd

Now I can change AAC normally from 'U' to something else.

In my test after customization I realize that I can change AAC from 'K' to something else in services POs too, only when I start creating my PO (derived from PR).

The field AAC become unchageable when I fill in a field in the Purchase Order (for example purchasing organization) before modify Account Assignment Category...I think it is a very strange behaviour for standard environment, do you have any suggestion?

Hi Fabio,

As far as I know that´s the standard behaviour. There are some checks in the system at the time of creating a PO, so when you fill any field the EKPO-KNTTP remains unchangeable.

You can check that this is hard-coded this way in program

SAPLMECO, in include LMECOU04 :

IF I_PSTYP EQ PSTYP-DIEN OR

I_PSTYP EQ PSTYP-BLNK.

• Dienstleistungspositionen nicht ändern

MESSAGE E456(ME) WITH I_KNTTP RAISING CHANGE_NOT_ALLOWED.

ENDIF.

Review note 570767 as well.

This is hard coded so you can not change the account assignment. Please

see the below code. You can set a breakpoint and test this.
