Hi,

In the Do loop in will fetch the all fields data one after the other starting from first field to Last field by incrementing one field.

Generally in FI data fetching and in HR wage Types data fetching we use this type of commands.

Hi Arnab,

here, in the DO loop we are fetching 10 records starting from f1 and varying it by one record as per the stmt. :

<b>varying it1-f1 from alpha0 next alpha1</b>

So here, 10 records one by one are fetched into the internal table <b>IT1</b>.

Hope this resolves your query.

Reward all the helpful answers.

Regards

Hi!

......VARYING dobj FROM dobj1 NEXT dobj2.

The addition VARYING assigns a new value at every loop pass to a variable dobj. This addition can be used several times in a DO-statement.

dobj1 and dobj2 are the first two in a sequence of data objects, which have the same distance from each other in the memory. The data type of the data objects dobj, dobj1 and dobj2 has to be flat.

In the first loop pass, the content of dobj1 is assigned to data object dobj, whereas in the second loop pass, the content of data object dobj2 is assigned to dobj. In the following loop passes, dobj gets the content of the data object, which has the same distance in the memory to the prior data object, like dobj2 to dobj1. There is no type conversion during this process.

Reward if useful.

HI...

Check this example..

DATA: BEGIN OF text,

word1(4) TYPE c VALUE 'This',

word2(4) TYPE c VALUE 'is',

word3(4) TYPE c VALUE 'a',

word4(4) TYPE c VALUE 'loop',

END OF text.

DATA: string1(4) TYPE c, string2(4) TYPE c.

DO 4 TIMES VARYING string1 FROM text-word1 NEXT text-word2.

WRITE string1.

IF string1 = 'is'.

string1 = 'was'.

ENDIF.

ENDDO.

Thanks
