Reproducing the Issue

Go to transaction code MIRO and input the posting date and reference date.
Input series of numbers or alphabets according to your business need.
You have noticed system will only handle 16 characters.

Cause

This is standard behavior.

Since ERP is being built up, reference document number (XBLNR) can only handle 16 characters.

The reference document (XBLNR) is not only defined/designed in MM area, such as invoice headers table RBKP, FI header table BKPF, (index for vendor validation of double document) BSIP, purchase order history table EKBE, goods receipt header table MKPF and other applications as well. As the result, for this matter, we can not provide system change, as it would be caused un-expect effect not just from MM, FI area, also other application processes.

Resolution

For duplication check, you may consider to fill up the "TEXT" field and develop your own program under FM MRMBADI_HEADER_CHECK in order to meet up with your requirement. However, this BadI is only valid from MM invoice process. Please notice that this is a workaround and SAP will not provide support for this custom solution.
