How to control item category in ME21n via authorization

Question

Hi,
When creating/changing PO in ME21N/ME22N how can I give access to only certain item categories via authorization objects.
Many thanks for your help.

Hi,
Please check the following:
If to a certain document type is assigned the 'blank' item            
category (Category Text : Standard)  for the document type in customizing ( Transaction olme ->              
Purchase Order -> Define Document Types -> Select Document Type 'ZSVC'             
-> Click Allowed Item Categories ), the system therefore would allow for the            
item category to be left blank when the PO is created/saved, even if the           
field selection key specifies it to be mandatory.Please note that in              
case of the item category, the field selection key customizing is                  
actually not considered here but only the item categories defined.                                                                               
If you would like to require an item category to be entered for the PO,            
then kindly delete the standard item category type and other item category types rom the customizing of              
the document type you use.
