IBP OBP Custom attribute in /IBP/MARC_EXT

[marziagambale]

Hello,

In IBP R&S we are using SAP7 for planning areas based on external master data. In S/4 ECC the CUST_ATTR4 field of table /IBP/MARC_EXT is of type date, while in IBP we have an attribute of type CHAR(10).

Is possible to modify the data element of the CUST_ATTR4 field in table /IBP/MARC_EXT?

Since the other Custom attributes are already valued for other purposes and only this one remains on which we should be able to bring a char field (and not a date) into IBP. 

Thanks

In general, is it possible to modify the data element of one of the ten predefined customer fields called CUST_ATTR1 to CUST_ATTR10 in the S/4 ECC tables /IBP/MARA_EXT?
