DFS877A DUPLICATE RECORD FOR LOGICAL PARENT (followed by one or more lines containing input records in hexadecimal and EBCDIC format)
Explanation
The issuing program found a type 00 input work data set record that was for the same occurrence of a logical parent/logical child pair as a previous input work data set record. Only one type 00 record can exist for a concatenation of a logical child and logical parent segment. This condition could be caused by supplying as input to the issuing program work data sets that were generated by multiple runs of a database initial load reorganization, or scan.
Programmer response
The result of prefix resolution is invalid. Determine the cause of the incorrect DFSURWF1 record. These records should be analyzed using the DFSURWF1 DSECT from the assembly of prefix resolution, DFSURG10, or IMS DSECTS module, DFSADSCT. If DBIL is used in PREREORG, then the logical parent concatenated key begins at offset X'19'. If DBR is used in PREREORG, then the LPARENT old address also begins at offset X'19'. The RBA address of this segment is at offset X'0C' in the DFSURWF1 record.
Ensure that only work data sets from databases currently being initially loaded, reorganized, or scanned are supplied as input to the issuing program.
