Hello experts,
a dump is returned if the code block below is executed. what would be the reason?

Thank you for your support.

 SELECT DISTINCT
 ml~aufnr,
 c~megbtr,
 c~plstar,
 c~gjahr,
 c~perio,
 c~belnr,
 c~buzei,
 c~objnr,
 c~uspob
 FROM mldoc AS ml
 INNER JOIN aufk AS a ON a~aufnr = ml~aufnr
 RIGHT JOIN coep AS c ON c~objnr = a~objnr
 AND c~kokrs = `1000`
 AND left( @p_jahpr, 4 ) = c~gjahr
 AND right( @p_jahpr, 3 ) = c~perio

 INTO TABLE @DATA(lt_data_plstar).

Try to simplify everything you can/writing differently:

1. AND left( @p_jahpr, 4 ) = c~gjahr → AND c~gjahr = @( substring( val = p_jahpr len = 4 ) )
2. AND right( @p_jahpr, 3 ) = c~perio → AND c~perio = @( substring( val = p_jahpr off = 4 ) )
3. RIGHT JOIN : can you change it to do a left join on MLDOC?
4. AND c~kokrs = `1000` → AND c~kokrs = '1000' (straight quotes instead of backticks)
5. AND ml~aufnr IN @lr_aufnr : What values do you have in LR_AUFNR ?
6. INTO TABLE @DATA(lt_data_plstar) : did you make sure the order of columns is same as the one in the SELECT, and types are exactly the same?

i noticed something:

if i does clear a lr_aufnr, solving problem. lr_aufnr defination an internal table(image.png). I found a duplicate data here and deleted one, still my problem persists.

By looping my problem was solved as follows. I haven't been able to identify the root cause though. What do you think about?

p_jahpr = 011.2021 (this problem is valid only for the 11th month)

    DATA: lr_aufnr TYPE RANGE OF aufk-aufnr,
          messages TYPE bapirettab.

The root cause is "memory allocation failed", you don't need to understand how the DB engine works, it would take too much time, but you can adjust till it works better. So, good that you found a solution. Also, search SAP notes like 2906305 - HANA Query fails in Join engine results (JERequestedAttributes) with Memory allocation fai......

Ok i understand. Thank you for help.
