function-pool

aidan_mulcahy — Wed, 05 Oct 2005 13:53:50 GMT

Hi,

I am implementing a BADI. In the method I call a SAP standard function. In the first line of the function I can see data in a table (no code at this point populates the table). This, I presume, has been populated by the function-pool the FM belongs to. I would like to see that table before calling the FM. Is it possible to declare the function-pool before I call the function so that I can see the table entries outside of the FM? In the code below the required table is 'gt_date_wrkt'. As you can see it is not populated in the FM itself.

Any suggestions?

method.....

...

call function 'CRM_DATES_READ_SINGLE_OB'

exporting

IV_DATESET_GUID = iv_ref_guid

IS_LOGICAL_DATE_KEY = lS_LOGICAL_DATE_KEY

importing

ES_DATE_WRK = ls_date_wrk

exceptions

PARAMETER_ERROR = 1

ENTRY_DOES_NOT_EXIST = 2

AT_LEAST_ONE_RECORD_NOT_FOUND = 3

ENTRY_IS_DELETED = 4.

.....

function crm_dates_read_single_ob .

statics: ls_date_wrk like line of gt_date_wrkt.

data: lt_dateset_guids type crmt_object_guid_tab,

lv_errorcode type sysubrc.

// check parameter

if iv_dateset_guid is initial and is_logical_date_key is initial.

message e103(crm_order_misc) raising parameter_error.

endif.

// read entry from object buffer

read table gt_date_wrkt into ls_date_wrk

with key guid = iv_dateset_guid

appt_type = is_logical_date_key-appt_type

is_duration = is_logical_date_key-is_duration.

Thanks.

If the table of MAin Function Pool is populated you can see it in the program ( BADI ) before calling the FM.

Try this -

DATA WA_NAME(50) vlaue

'(<MAIN_PROG_FUNC_POOL>) gt_date_wrkt[]'.

FIELD-SYMBOLS <F1> TYPE ANY .

ASSIGN WA_NAME TO <F1>.

IF SY-SUBRC EQ 0.

IF NOT <F1> IS INITIAL .

ENDIF.

ENDIF.

You will have to find the name of Main program of function and then replace it in above code .

Cheers.

Sanjay,

I have never used Field Symbols. How do I access the data once I have assigned the F-pool? There is a field in the gt_date_wrkt table called 'APPT_TYPE'. What would I do to read that?

Thanks,

Aidan.

You can see only data defined in Function - Pool in this way provided it is available at runtime .

Define a similar internal table in your program .

"APPT_TYPE" seems to be a type defined in that function pool as I cannot find it in the dictionary.

Now put this code in your program

DATA ITAB LIKE APPT_TYPE OCCURS 0 WITh HEADER LINE.

( Above line may change as I am not sure how APPT_TYPE looks like )

DATA WA_NAME(50) vlaue

'(<MAIN_PROG_FUNC_POOL>)gt_date_wrkt[]'.

FIELD-SYMBOLS <F1> TYPE ANY .

ASSIGN WA_NAME TO <F1>.

IF SY-SUBRC = 0.

ITAB[] = <F1>.

ENDIF.

Now Itab will be similar to what you have in gt_date_wrkt . You can loop on it or do whatever you want. <MAIN_PROG_FUNC_POOL> will be main program of actual function group name which you have not mentioned so far in your post.

Cheers

Sanjay,

thanks again.

I am getting a short dump and the issue seems to be that that line is trying to assign a character string to an internal table.

The data is available at runtime (within the function module). e.g. The data I need is in gt_date_wrkt (table of CRMT_DATE_WRKT). In the code:

*********

method IF_EX_CRM_PRICING_BADI~CRM_PRICING_MERGE.

....

DATA WA_NAME(50) value '(SAPLCRM_DATES_OB)gt_date_wrkt[]'.

FIELD-SYMBOLS <F1> TYPE any.

DATA ITAB type table of CRMT_DATE_WRK.

ASSIGN WA_NAME TO <F1>.

IF SY-SUBRC EQ 0.

IF NOT <F1> IS INITIAL .

itab[] = <F1>. ~~Short Dump here~~

ENDIF.

....

I need the data here but it is not available

call function 'CRM_DATES_READ_SINGLE_OB'

-> the table is populated automatiaclly within the FM

*********

Maybe I am not understanding the Field Symbol but it looks like it is just try to assign a string of text to the itab?

Thanks,

Aidan.

Hi Aidan,

You are almost there . Seems to be the ITAB definition causing the problem.

Try these in sequence.

1) Put a break point on IF NOT <F1> IS INITIAL and check the contens of <F1> in debugging. If asigned correctly then you will see its a table with one or multiple lines.

2) Now what is requirement .

IF <F1> is not initial means the internal table has data . You just want to check if internal table has data or you want to process it . If you want to process , just try below code . If you just want to check if itab has data then IF <F1> is not initial is sufficient .

data wa type CRMT_DATE_WRK.

...

IF NOT <F1> IS INITIAL .

LOOP AT <F1> INTO WA.

ENDLOOP

ENDIF.

Also give the details of dump. But try in debugging , it will be more helpfull.

Cheers

This seems to be the issue. <F1> is not initial but it is not a table, it is just a character string:

DATA WA_NAME(50) value '(SAPLCRM_DATES_OB)gt_date_wrkt[]'.

FIELD-SYMBOLS <F1> TYPE any.

ASSIGN WA_NAME TO <F1>.

The result in debugging is:

<F1> = '(SAPLCRM_DATES_OB)gt_date_wrkt[]'.

So, when I loop at <F1>, it just fails.

I presume what should be happening is that the F-pool is accessed and gt_date_wrkt would be available?

Are my definitions OK?

Thanks,

Aidan.

Sorry about that .

The correct statement is

ASSIGN (WA_NAME) TO <F1>.

( Now I think you previous code

itab[] = <F1> . should work )

Most of the problems you solve in debugging.

In debugging just put (SAPLCRM_DATES_OB)gt_date_wrkt[]

in the field name and you can see the data .

Cheers

Sanjay,

that did it. Thanks a lot for your help. Just in time too.
