DATA-INTO problem

I have gained access to an API and am receiving four test records, but they are not loading to the database. The docsReady array is blank except that the num_Docs field of each element contains the same value (1077952576.)

I am getting a message:
Error MCH3401 occurred while running the program or procedure for the DATA-INTO

I don't know what I may be doing incorrectly. Can you help?

Thank you,
Scott

groupID ZONED(5:0);

sequence ZONED(3:0);
priaDocObjectID ZONED(6:0);
