3268822 - Field Control in Purchase Orders and Purchase Requisitions in S/4HANA Cloud

• There is no SSCUI entry to change the Field Properties on Purchase Orders or Purchase Requisitions.
• The user wants to mark the fields as hidden, optional, or mandatory.
• There is no configuration entry with this purpose, this functionality is delivered through BAdIs to give more flexibility on the Logic for Field control.

SAP S/4HANA Cloud Public Edition

The user must use the below BADIs, please go to the App Custom logic to find more details and an example*

Note:

The BAdI Change of Field Control for Purchase Order Items (MM_PUR_S4_PO_FLDCNTRL_SIMPLE) allows the user to influence the field control of the above-mentioned fields. It does not perform any checks that may be required after the change of the status properties.

For example, if user's BAdI implementation defines the status of a field as 'Mandatory' that SAP has defined as 'Optional', the system does not perform a check and does not output an error message.

The user can implement the BAdI Check of Purchase Order Before Saving (BD_MMPUR_FINAL_CHECK_PO) to perform their own checks and to output the corresponding error messages.

* Example taken from Custom Logic:

To change the field control properties, assign one of the following values to FIELDSTATUS:

• '-': To hide the field
• '*': To make the field read-only
• '+': To make the field mandatory
• '.': To make the field optional

Example Implementation:

FIELD-SYMBOLS <fs> TYPE mmpur_s_pr_fldsel.

READ TABLE fieldselection_table ASSIGNING <fs> WITH KEY field = 'PRODUCTTYPE'.

IF sy-subrc EQ 0.

<fs>-fieldstatus = '*'.

ENDIF.

Implementing this piece of code makes the field Product Type read-only in purchase requisitions.
