Issue with PO Line Distrib EE_SEQ_NUM - Causing budget check issues

Peopletools 8.60.09 PUM 48.

We have encountered an issue with PO budget checking; when some users add a distrib line on a PO and budget check the PO they get message: The Purchase Order cannot be save(10200,732) Because Budget Processor is Running against this document in the background.

We have to update the ee_seq_num on the PO_LINE_DISTRIB table and update the budget_hdr_status on PO_HDR to 'N' for the PO to budget check Ok.

Has anyone had this Issue?

Any input is much appreciated
