Recursive Function Module

[Former Member]

Hi Experts!!

I have two tables A and B.

A has two value 10

20.

B is empty here.

{Loop at A.

Call Fuction ' Find_Value'

Export

em_a = A

Import

im_b = B.

Endloop.}

here b has 3 records

75

25

39

case-2: I want to call same function module.

I want pass B value here till following condition satisfy. Let Say 10times.

Problem is I dont want to call same function module again and again.

{loop at B.

Call Fuction ' Find_Value'

Export

em_a = B

Import

im_b = B.

Table B,Field A = Table A Field C.

if B-A = A-C

Exit.

endif.

Endloop. }

Please suggest how to call above Fuction Module recursively for all value...in B.

Any clarification appreciated.

Please suggest.

use a local variable to assign the value of B.

and after calling the FM, update B.

keep calling the FM in a loop until and unless until the value of prev B = the local variable.

Hi,

Thanks for your quick reply.

But how to do that.

if B has 3 values, again each record giving me multiple import value. I have to again pass the same function module to find their subtransaction values.

when condition not satisfied , then quit.

Please give me example if any u have.

Hi anee,

use do...while loop.

declare a flag

Data flag type c.

do

if sy-index eq 10.

flag = 'X'.

endif.

call function

Export

tab = B

IMPORT

tab = B.

while flag <> 'X'.

it will call the same function 10 times.

Reward if helps.
