item category

Question:
Hello!
1. I have recently created a new puchasing document type , which i want to use only for procurement of assets. So in the account assigment only 'A' should be allowed. I understand that we can link the item category to the document type.
The item category is again liked to the account assignment.
Now my problem is which item cateogry should i link to the new document type , such that only 'A' is allowed in account assigment, not even blank.
2. Can i create new item categories?
Thankyou,
Answer:
Hi,
I would recommend another alternative solution by setting up the Field selection at document level via Field Selection Key. At first, go to Transaction OME9 and make sure that the 'Asset Number' field is set as mandatory for Account Assignment Category 'A'. Then go to Transaction OMEC and select different Field Selection Key (for instance, NBF for standard PO and MBF is for your special PO). After these two steps were completed, go to Transaction OMF4 and respectively define the field selection for these two Keys where for NBF, the field 'Asset number' is set as 'displayed' or 'suppressed' whereas for the remaining MBF, this field is set as mandatory. If the end user forgets to select the standard PO document type, then he can not post it.

Answer:
Thankyou very much for your reply.
i tried what you suggested, but now the problem is :
now the account assignement category is compulsory and the user can enter any account assignment (like k, p,etc).
we want the user to enter only 'A'.

Hi,
This can be simply set via transaction OMEC for your new document type where only Item Category 'A' is permitted.

Answer:
Hi,
Sorry for my previous posting since I was thinking of the Item Category instead of Account Assignment Category 'A'. What I can say is that if this is the specific document type for only account assignment category 'A', then you have to use the User Exit which will validate the account assignment category 'A' with the document type to be selected.
