Read structure FIELD Dynamically

Former Member — Mon, 07 Aug 2006 10:28:42 GMT

Hi All Experts,

I am working on CO-PA exit EXIT_SAPLKEAB_001.

In this exit we have a structure EP_SOURCE. This structure gets its structure dynamically. In my case this is of type CE1SN00. These CE1 tables gets generated in SAP dynamically when you maintain any Operating Concern in CO-PA. In my case Operating concern SN00 has been maintained. And in this CE1SN00 there are multiple Value fields. I have to apply a formula on one of the fields.

The problem is that I have to apply a formula on different fields everytime. I have a Z table which has fields 'Operating Concern', 'Field' and 'Active Indicator'. I have to read this Z table based on the Operating Concern and get the 'Field' name.

For example in my Z table if I have a Operating Concern 'S_AL' and field 'KWBLOK_ME'. And the EP_SOURCE structure has got an entry from table 'CE1S_AL'. I have to read 'EP_SOURCE-KWBLOK_ME' and apply the formula on it.

And next time if I have a Operating Concern 'S_AL' and field 'KWFLHR_ME'. I have to read 'EP_SOURCE-KWFLHR_ME' and apply the formula on it.

What I have done so far is I have defined a structure IT_CE1S_AL as type CE1S_AL and moving all the values from EPSOURCE to IT_CE1S_AL. Now I have to read the value of only that field which is there in 'Z' table.

I hope I have explained this well. Please help me in solving this problem.

Hi,

Check this FM : DYNP_VALUES_READ to read the field values.

Try this:

FIELD-SYMBOLS: <f1> TYPE ANY, <f2> TYPE ANY, <f3> TYPE ANY.

ASSIGN EP_SOURCE TO <f1>.

ASSIGN 'S_AL' TO <f2>.

ASSIGN COMPONENT <f2> OF STRUCTURE <f1> TO <f3>.

<f3> contains the required value

Hello,

Take your all fields into an internal table from your Ztable.

field-symbols:<f1> type any.

Loop at itab.

itab-fld = 'KWBLOK_ME' .

assign component itab-fld of structure CE1S_AL to <f1>.

now you have values in the <f1> as

f_value = <f1>.

endloop.

regards,

Naimesh

hi Rajesh

You need to use field symbols for this...

here is the sample code.

field-symbols <fs1>.

loop at itab.

itab-field1 = 'KWBLOK_ME' .

Assign the itab-field1 of structure CE1S_AL to <f1>.

You have the values in <f1> as

value = <f1>.

*You can apply the formula here..

endloop.

Hope this will help you.

Regards,

Richa

Hi Appana,

Thanks for your reply, but this won't solve my problem, here I am trying to read a structure in a user-exit and want to read one field only from that structure and this one field could be anything.

For example: I have a structure called MARA. In first instance I want to read MARA-ERSDA because ERSDA is there in my 'Z' table and in second instance I might have to read field MARA-LAEDA because the ERSDA field has been replced by LAEDA now in the 'Z' table.

Cheers!!

Hi Richa,

Thanks for ur reply. But my requirement is something different. I have tried the field symbols but getting an error message - "Data object 'EP_SOURCE' does not have a component called <FS1>".

Once again my requirement is:

I have a Z table ZCO_VALUE. The structure of the table is:

_______________________________________

MANDT | OP_CON | FIELD | A_IND |

And there 2 two entries in this table:

_______________________________________

100 | S_AL |KWBLOK_ME | A |

100 | S_AL |KWBLHR_ME | A |

And I have a structure EP_SOURCE in user-exit which is just like CE1S_AL. KWBLOK_ME & KWBLHR_ME are technical field names in CE1S_AL. I want to read the value of either CE1S_AL-KWBLOK_ME or CE1S_AL-KWBLHR_ME.

Now in my first instance I want to read

EP_SOURCE-KWBLOK_ME, but I have KWBLOK_ME as a value in ITAB_ZCO_VALUE. I have defined a field-symbol <fs1> to get values KWBLOK_ME or KWBLHR_ME. And trying to read by write the code as:

get_value = EP_SOURCE-<fs1> or

Assign ep_source-<fs1> to get_value.

But because ep_source is not referenced to any structure I can't use any of the above statement.

Thanks

Hi,

Thanks a lot.

This Assign component statement solved my problem.

Many Thanks.

Have a Nice Day

Hi Vijay, Naimesh, Richa:

Thanks to All.

I have got my code working now.

I was using ASSIGN statement only. Silly Me.

By using ASSIGN COMPONENT I got what I want.

Many Thanks to All of YOU who replied to my post.
