Simple doubt in BDC Call Transaction Method

[Former Member]

Hi Friends,

When i try to call vk13 transaction and pass the screen field values for the second screen and execute it it is displaying properly.But when i try to pass the different value in the bcddata internal table it is changing properly but in the screen it not updating that value.Alawly the screen fields are taking the values passed the first time.But in the internal table which we are oassing to the calltransaction it is changing correctly but not in the corresponding screen fields. Why it is happening so. Can any one help me out of this problem.

Thanks in Advance.

HI,

After CALL TRANSACTION you should refresh BDCDATA internal table.

Are you doing this?

while passing from internal table after 1 record has been passed, clear the header of the internal table...then pass the second record...

also, after first record ru saving the data and then passing the second record.

Hi

After inserting price type in VK13, a report is called and I don't believe a BDC can work with selection-screen.

U can directly do a SUBMIT.

The name of the report should be RV13XXXX, where XXXX is the table number of the sequence you've chosen

I am not passing through the selection screen . It is like iteractive report. when i select the particular line in the list output then the screen fields should take the values from that selected line. First time when i select the line it is taking properly.

But next time when i select the line the content of the i_bdc_tbl is changing correctly but when it enter in to the transaction it is not taking the values from the i_bdc_tbl. Simply it is displaying the screen fields with the old values. It is not updating the screen fields with the values from the i_bdc_tbl. Why the screen fields are not replaced with the value of i_bdc_tbl? Why it is not getting refreshed with the new values?

Just i am posting the bdc portion of my code here. So you can help me out on this.

Hi Ram,

You need to Refresh the BDCDATA table every time, i mena this statment should be in the loop starting point or end of the CALL TRANSACTION statment ..

I have done that in both place even then the same problem only. When i enter in to the tansaction again the screen fields are not refreshed it is having only the old values.

[former_member69765]

Very simple.... refresh BDCDATA table before u populate with next record...

[Former Member]

Hi Ram,

I think i understood your Problem, It is not with Refreshing, may be you have not included the statements inside the LOOP ....... ENDLOOP.

Loop at Itab_bdc. " BDC Internal table in which you have the records.

...

...

Endloop.

Reward Points if found usefull.

Cheers...

I am just having single record at every line selection of list output. So i think no need to loop that table.
