On AS400 the transfert is stopped with a DIAGI 106 and a DIAGP 57010D01
The code 57010D01 means: "Sequential READ on keyed file failed".
That relates to a  file with key ("Keyed DataSet"), which come, generally, of Database.
These files with key can include recordings removed with a "Flag¿" and for this reason are not supported by CFT. The "file Management" used by CFT to read the files to be transferred cannot read these recordings with a "Flag" and is stopped with the error code "57010D01".
Generally, these file do not include a record with a "Flag", which explains why CFT can treat them.

Make a copy of this file with order "CPYF" to transform it into "PF Dated" without the concept of keys, and to transfer the file copied.
