  The SAP error message OIUCM030, which states "At least one child record must exist," typically occurs in the context of the SAP Oil and Gas (O&G) module, particularly when dealing with master data or transaction records that require associated child records.
  Cause:
  This error usually arises when you are trying to create or modify a parent record (such as a contract, master data, or a similar entity) that is expected to have at least one associated child record (like line items, sub-contracts, or related transactions), but none exist. The system enforces this rule to maintain data integrity and ensure that parent-child relationships are properly established.
