Data decimal error when running MRP in test environment

I just refreshed our test environment from tape and when we run MRP in test,
we get the following error:

Message . . . . :   AMM34 2019 decimal-data error in field (C G S D F).

Cause . . . . . :   The RPG program AMM34 in library XAR55PTF found a

  decimal-data error at statement 2019. One field did not contain valid

  numeric data.  The digit and/or sign is not valid. Recovery  . . . :
Enter
  C to cancel, G to continue processing at *GETIN, S to obtain a system
dump,
  or D to obtain an RPG formatted dump. Possible choices for replying to

  message . . . . . . . . . . . . . . . :   D -- Obtain RPG formatted dump.
S
  -- Obtain system dump. G -- Continue processing at *GETIN. C -- Cancel. F
--
  Obtain full formatted dump.

I cannot understand why we get this in test and not production.  I used last
night's back up tapes to refresh the test environment and MRP ran
successfully last night.  I refreshed the test environment today from tape
and we immediately ran MRP.  A programmer suspects it is somehow related to
refreshing from tape and believes I need to refresh using the menu option in
CAS.

Any suggestions on how to solve this?

Thanks in advance.
