How to use dynamic colums with conditions into SELECT statment in AMDP?

Dear SAP HANA Experts,

Recently, I am digging on AMDP for leveraging performance of programs. Meanwhile, I need some help to change/adapt AMDP method concurrently as applying dynamic SQL in AMDP. I know it causes leading performance regression, but I require to use it for creating universal AMDP method to adapt everywhere.

These are the questions on the below I need answers:

1. Is it possible to apply Dynamic SQL in AMDP?

(For example)

DECLARE LV_SEL STRING;

  LV_SEL = 'SUM(VV500) AS VV500, SUM(VV501) AS VV501, SUM(VV500+VV501) AS VF501;

  LV_TABLE = 'CE1XXXX';

ET_CE1XXXX = SELECT <LV_SEL>

                               FROM <LV_TABLE>

                            WHERE MANDT = '100'

                                  AND KOKRS = 'XXXX'

                                  AND BUKRS = 'XXXX'

                                  AND SPMON = '201509';

2. Or, is it possible to use Dynamic procedures in AMDP? (if yes, can you give me sytax for example?)

The purpose of two questions are the same. I want to use dynamic colums with conditions into SELECT statement.

Is any other way to solve this problem? Please feel free to give me any answers to solve this.

Thanks,
