ABAP Loop Question for next record

[Former Member]

Hello All, I am new to ABAP so please forgive this basic question. The below is a snippet of code I have in a ABAP Proxy.

Here is a snippet of my code:

DATA: ls_item TYPE ZSHOPPING_CART_IN_BBP_PDS_SC_I.

DATA: i_item TYPE TABLE OF bbp_pds_sc_item_icu.

DATA: w_item TYPE bbp_pds_sc_item_icu.

....

LOOP AT input-I_ITEM-item INTO ls_item.

CLEAR w_item.

w_item-guid = v_item_guid.

w_item-parent = v_header_guid.

w_item-description = ls_item-description.

w_item-number_int = ls_item-number_int.

w_item-category = ls_item-category.

w_item-category_id = ls_item-category_id.

w_item-product_type = ls_item-product_type.

APPEND w_item TO i_item.

ENDLOOP.

---

The structure input-I_ITEM-item is an input from a ABAP Proxy. This all works great if I feed in only 1 line item to proxy, but if I send in two line items the result is i_item has line item 1 twice, and I get nothing for line item2. It is almost like the the loop runs twice but the ls_item stays on line 1. I am sure I am missing something simple.

CLEAR ls_item after the APPEND statement.

Hi Suresh,

I added the CLEAR ls_item. after the Append but I still get record 1 twice.

I_ITEM seems to be a structure and NOT LINE TYPE.

Rajesh - You are right. CLEAR clears header area.

Try clearing like this:

LOOP AT input-I_ITEM-item INTO ls_item.

CLEAR w_item.

w_item-guid = v_item_guid.

w_item-parent = v_header_guid.

w_item-description = ls_item-description.

w_item-number_int = ls_item-number_int.

w_item-category = ls_item-category.

w_item-category_id = ls_item-category_id.

w_item-product_type = ls_item-product_type.

APPEND w_item TO i_item.

<b>CLEAR i_item.</b>

ENDLOOP.

Thanks,

Hi SKJ,

If we clear an internal table with out header line(i_item) then the contents of the table will get deleted. Correct me if I'm wrong.

Hi SKJ,

When I add CLEAR i_item. I get no lines outputted.

Hi,

Check if the internal table <b>input-I_ITEM-item</b> has two different rows..

Here is a snippet of the XML I am sending to ABAP proxy:

<I_ITEM>

<item>

<GUID>00000000000000000000000000055556</GUID>

<PARENT>00000000000000000000000000055555</PARENT>

<NUMBER_INT>0000000001</NUMBER_INT>

<DESCRIPTION>Proxy Test Line</DESCRIPTION>

<CATEGORY>268CA1C5BB9965449BED8C9B49484999</CATEGORY>

<CATEGORY_ID>03000</CATEGORY_ID>

<PRODUCT_TYPE>01</PRODUCT_TYPE>

</item>

<item>

<GUID>00000000000000000000000000055557</GUID>

<PARENT>00000000000000000000000000055555</PARENT>

</item>

</I_ITEM>

Hi Joe,

check the values of the fields

ls_item-description,

ls_item-number_int,

ls_item-category,

ls_item-category_id,

ls_item-product_type in debugging,

ensure that they are different for the 2 line items.

Hi All, Maybe this will help. When I remove all clear statements and move the APPEND w_item TO i_item outside the ENDLOOP, it writes only the second line from input-I_ITEM-item. So this shows I have two lines but seems to be a problem with my routine moving to next line. Not sure hope this helps.

Cheers,

You sure this is correct? These values are not coming from LS_ITEM?

w_item-guid = v_item_guid.
w_item-parent = v_header_guid.

Hi Rich,

Looks like you are correct in that because I am not passing the item-guid as a unique value both records are using the same guid resulting in the record showing as duplicates. I will work through the logical and determine what is wrong, but it looks like it is not an issue with moving through the loop.

Thanks Everyone,

J
