modify statement

[Former Member]

Hi friends.

a)

read table it_zsat into wa_zsat with key matnr = '5003' binary search.

if sy-subrc = 0.

wa_zsat-ERNAM = 'FERT'.

modify it_zsat from wa_zsat index sy-tabix .

endif.

b) read table it_zsat into wa_zsat with key matnr = '5003' binary search.

if sy-subrc = 0.

wa_zsat-ERNAM = 'FERT'.

modify it_zsat from wa_zsat index sy-tabix transporting ernam.

endif.

performance wise which one should i use in my program and why.

Hello

Yes.

In first case the complete line is moved.

In second case only selected component is moved.

Hi,

I suggest use Field-SYmbols instead of using MODIFY... Performanace wise it is very good.

FIELD-symbols : <f2s1> TYPE wa_zsat.

read table it_zsat assigning <fs1> with key...

if sy-subrc eq 0.

assign the value.

endif.

regarding to ur question: using Tranporting will perform good. (2nd Modify)

Hope it helps!!

Hello Pavan,

Can you share the source for your claim?

i mean if we use transaporting field name ie : transporting ernam it will only modify that particular field and if i dont use transporting then it will try to modify all the fields of work area even though if i dont chnage the value... is that correct....?

[Former Member]

Yes, u r correct, it will modify only the values only for those u assign a new value after READ...

Hello Satish,

An F1 on MODIFY stmt will answer these queries.

Your question is answered by that explanation 😮

Hi,

read table itab assigning <fs1> with key ...

binary search..

if sy-subrc EQ 0.

ASSIGN 'FERT' to <fs1>-matnr.

endif.

I think if u take F1 help from SAP, u ill more understand with an example...

And where does SAP F1 talk about the performance ??

[Former Member]

Thats the reason i have posted here.

if i was just using forum then the question would not have been on performance based.

just checked the F1 help then later i posted it here guys...

Hi Satish,

2nd statement is better in performance, when u have a complex structure....

so,its better to go for the modify statement with transporting rather than modifying alone..
