MAPPING TRACEDATA

The MAPPING_TRACEDATA parameter recovers changes made to the fields.

MAPPING_TRACEDATA=1 recovers field changes

   Format: LIB.FILE(FIELD)=VALUE

Level 1 of DB.MAPPING_TRACEDATA shows us the values of the fields once they are assigned.

Level 2 shows us the values of the fields when they are accessed. This gives more detail in calculations for instance.

Example:

The following calculation would be:

   DB.integer3 = $DB.integer1 -$DB.integer2

At level 1: DATA : .DB(integer3)=12

At level 2:

DATA : .DB(integer3)=(null)

DATA : .DB(integer1)=15

DATA : .DB(integer2)=3

DATA : .DB(integer3)=12
