CICS BMS map display

[Guest_imported]

In one of our application we have this flow of screen.
screen B -> screen C -> screen D and map of screen D display correct data.
For this scenario
screen A -> screen B -> screen C -> screen D and map of screen D display corrupted data.
Always O field of the screen have correct value but for second sequence of screen the map comes out corrupted.
Can any body provide some clue.?
My guess is there is some kind of memory overflow. Do not knpw how to pinpoint it.
Any help is appreciated

Fire CEDF and check what is happening
i have a feeling you are missing low-values to one of the maps
