Jeff,
Use (or get your CNC to use) the JDE Object Configuration Manager, application P986110, fast path OCM, select System (not server map). In the Primary Data Source column in the Query By Example (QBE) line, use the search torch and select your save data source. Then click find. Now select all the lines that active (Status AV) and click the row exit Change Status to disable them.
If there are lines that are inactive (Status NA) or no lines returned at all - let us know if this is the case, the problem may be that there are no active OCM entries for the save location.
At this point try the delete.
Whether or not the delete works, set the OCM entries back to active by following the procedure above, but selecting the lines that are inactive (Status NA).
