Calling modules on screen flow logic based on some condition

[Former Member]

Dear All,

I am developing a function module with few screens. My busienss requirement is such that i need to use some standard Module code, not this call should be conditional, and should be called only for the first time when screen is loaded.

I can not use chain end chain conditions as i am not giving any field open to users to load data.

Please sugegst.

Thanks for your help.

Hi,

As per my understanding, u can write those nodules in PBO of the screen and then set a flag variable 'Y', in the end of that modules.

and check a condition that if flag <> 'Y', then only that code is executed.

So firset time when the screen will be loaded , flag will not be y and that modules will be executed, but nest time those will not be executed.

Hope it helps.

Hi,

we can write out any logical (comparison statement ) expression on screen flow logic.we can only write modules i that but in that module u can put the condition to execute that code.

for example

PROCESS BEFORE OUTPUT.

MODULE STATUS_1000.

MODULE SELECT.

MODULE SELECT OUTPUT.

IF FLAG <> 'Y'.

SELECT A_{MATNR A}EBELN EBELP MENGE LIFNR A~WERKS

FROM EKPO AS A INNER JOIN EKKO AS B

ON A_{EBELN = B}EBELN

INNER JOIN MARC AS C

ON A_{MATNR = C}MATNR

AND A_{WERKS = C}WERKS

INTO TABLE ITAB_TC

WHERE A~EBELN = EKPO-EBELN

AND BSART IN ('ZIMP' , 'ZPO')

AND A~LOEKZ = ' '

AND A~RETPO <> 'X'

AND SERNP = 'Z003'

.

flag = 'Y'.

ENDIF.

ENDLOOP.

Hope it helps.

Please look at the code. i have to call module test1 based on a flag condition.

PROCESS BEFORE OUTPUT.

field TEST_VAR.

module status_modelling.

IF TEST_VAR '0'.

module test1 .

ENDIF.

but i am gettign error for this

[former_member632991]

Hi,

it will give error like this,

write the if condition in the module.

instead of this

<b>IF TEST_VAR '0'.

module test1 .

ENDIF</b>.

write like this.

<b>module test1 .</b>

IF TEST_VAR '0'.

<b>write ur code here.</b>

ENDIF.

<b>endmodule.</b>

I want to call Module tes1 only and only when condition is successful..

Not sure if this will help.

cause i can not modify these modules,(part of standard program)

To call the module only once you will have to set a Flag inside your module. This cannot be done in the screen flow logic as IF conditions dont work there.

So Basically

<b>MODULE Screen_100 Output.

if flag is initial or if condition is successful.

Write ur code here.

flag = 'X'.

endif.

ENDMODULE.</b>
