DFS075I REQUESTED BLOCK NOT AVAILABLE: MID name
Explanation
The Message Format Service (MFS) cannot fetch the control blocks required to process an input message. The message identifies the MID name for the MID and DIF pair requested. The MID or DIF contains an invalid field, which is probably caused by modification or damage to the Format or Test Format libraries.
System action
MFS ignores the input message.
Programmer response
Stop using the transaction requiring this MID or DIF, or both, block long enough to allow the blocks to be replaced by others from the Message Format Library. Then retry the failing transaction. If the error persists, the blocks were damaged in the Format or Test Format library, an error was compiled into the blocks, or an error exists in an MFS online module.
