what does CHANGEDOCUMENT_READ_POSITIONS do?

Former Member — Mon, 07 Jul 2008 10:29:26 GMT

hi,

i have a FM CHANGEDOCUMENT_READ_POSITIONS

i have filled i_cdhdr from the database table CDHDR.

and then i provide all the change numbers present in i_cdhdr to the function module CHANGEDOCUMENT_READ_POSITIONS and receive i_cdshw..

but since i can only provide one change number at a time i have to call this function in a loop on internal table i_cdhdr.

is there any other function module which can give me all the entries in i_cdshw when i provide a single table i_cdhdr?

or can i implement the above logic with a select query on CDPOS? if yes, how?

thanks for the help.

u can i implement the above logic with a select query on CDPOS

check this

if not i_cdhdr[] is initial.

select * from cdpos

into table i_cdpos

for all entries in i_cdhdr

where cdpos-OBJECTCLAS = i_cdhdr-OBJECTCLAS

and cdpos-OBJECTID = i_cdhdr-OBJECTID

and cdpos-CHANGENR = i_cdhdr-CHANGENR.

endif.

Cheers,

Snehi.

hi snehi,

but we are not using i_cdhdr but rather i_cdshw which is included in tables section..

so, we are more interested in getting i_cdshw which has completely different structure than cdhdr and cdpos!

I_CDSHW provides the old value and new value with addition of units, i got the same values by firing a select query on CDPOS but without units.

so, i had to pick up the part of code which was attaching unit in the value and include that in my code.

thanks a lot for help.
