Currently we have issue while creating work order.
After input all required field for creating work order (T-Code IW31/IW34), work order number saved with number 4000020. But when performing change or display respective work order. there's message shown " Express document "Update was terminated" received from author" and routed to business workplace inbox an notified as SAPSQL_ARRAY_INSERT_DUPREC for the error info.
We have checked from table AUFK and no work order 4000020 available. Also, check the number range and seems no problem there.
