left() in CE_FUNCTIONS

Hi @ all,

we have the following sql statement in a calculation view.

var_out = select vbep.mandt, vbep.vbeln, vbep.posnr, max(left(mbdat,6)) as mbdatmax, sum(bmeng) as bmeng, vbep.lifsp

from "FP3040"."VBEP" vbep

group by vbep.mandt,




Would it be possible to receive the same result with CE_Functions?

We tried the following but it seems that the combination of max(left()) is not feasable within CE_AGGREGATE().

var_table = CE_COLUMN_TABLE("FP3040"."VBEP", ["MBDAT", "BMENG", "MANDT", "VBELN", "POSNR", "LIFSP"]);

var_out = CE_AGGREGATION(:var_table, [max(left("MBDAT", 6)), sum("BMENG")],["MANDT","VBELN","POSNR","LIFSP"]);

Thanks a lot for you input.

    Hi Florian,

    You can do almost everything on CE but it's normally needed more instructions (One SQL can sometimes require 6 or more steps to achieve same result), try the projection below for your case:

    var_table = CE_COLUMN_TABLE("FP3040"."VBEP", ["MBDAT", "BMENG", "MANDT","VBELN", "POSNR", "LIFSP"]);

    var_proj = CE_PROJECTION(:var_table,


    CE_CALC(' leftstr("MBDAT",6) ',VARCHAR(6)) as "PERIOD"]);

    var_out = CE_AGGREGATION(:var_table, [max("PERIOD"), sum("BMENG")],["MANDT","VBELN","POSNR","LIFSP"]);

    Regards, Fernando Da Rós
