To validate a group of fields we use those fields in between
CHAIN

ENDCHAIN

Answer / ajoy chakraborty

You cannot perform input checks in PAI modules of programs
until you have transported the contents of the input fields
to the ABAP program. You can then use logical expressions to
check the values that the user entered. You should then
allow the user to correct any wrong entries before calling
further modules.

CHAIN.
FIELD: <f1>, <f 2>,...
MODULE <mod1>.
FIELD: <g1>, <g 2>,...
MODULE <mod2>.
...
ENDCHAIN.

all of the fields on the screen that belong to the
processing chain (all of the fields listed in the field
statements) are made ready for input again. Other fields are
not ready for input. Whenever the MODULE statement appears
within a processing chain, even if there is only one FIELD
attached to it, all of the fields in the chain (not only the
affected field) are made ready for input again, allowing the
user to enter new values. If the fields in the processing
chain are only checked once, the PAI processing continues
directly after the FIELD statement, and the preceding
modules are not called again.
