Maximum record length in internal table?

Former Member — Thu, 17 Jul 2014 16:35:28 GMT

Is there a maximum record length in an internal table? Please note: My question is NOT related to table space. I'm referring only to the length of an individual record (A.K.A. row length).

I am using a work area to insert data into an internal table. Both the work area and internal table are defined by the same structure.

The structure has a total length of 672 bytes. For the sake of this discussion I'll point out that at the end of the structure, bytes 669, 670, 671, and 672 are four separate fields of 1 character each.

When viewing the work area record in the debugger I'm seeing all the fields and all the values. When viewing the internal table in the debugger after a record is inserted, the internal table ends with the field defined at Byte 670. The internal table does not include the two fields defined at Bytes 671 and 672.

Am I to assume from the above explanation that the length of a record ( A.K.A. row) in an internal table cannot exceed 670 bytes?

Thank you.

Can we have a screenshot and some ready to paste code so that we can reproduce this on our systems?

Manish,

False alarm! While, technically, you didn't answer my question, your request for code ended up helping me answer my own question.

To provide you with some code I wrote a simple test program using the record layout referred to above, with a DO loop to put some records into the internal table, followed by a LOOP AT, with accompanying WRITE statements to display the contents of the internal table and demonstrate that the last two fields weren't being stored.

However, when I ran the test program, the last two fields were being displayed.

It was at that point, when stepping through the debugger that I noticed the scroll arrows above the last column of my internal table that allowed me to scroll to the right and see my final two fields.

Apparently, because of the large number of fields in my internal table I had reached the default display length of the debugger. While I was obviously aware of the scroll bar found at the bottom of the display, I had never worked with an internal table of that width in the past and hadn't even noticed the scroll arrows above the last column before.

Thanks for taking the time to respond helping me get to the solution.
