When processing a loop with the statement DO... ENDDO, the system variable that contains the implicit loop counter is sy-index. The loop counter is a numeric value that indicates how many times the loop has been executed. The loop counter is initialized to 1 before the first execution of the loop and is incremented by 1 after each execution. The loop counter can be used to control the number of loop iterations or to access the loop elements by index.The loop counter can also be accessed or modified within the loop body, but this is not recommended as it may cause unexpected results or errors1.

For example, the following code snippet uses the loop counter sy-index to display the numbers from 1 to 10:

DO 10 TIMES. WRITE: / sy-index. ENDDO.

The output of this code is:

1 2 3 4 5 6 7 8 9 10

ABAP SQL arithmetic expressions have different restrictions depending on the data type of the operands. The following are some of the restrictions:

Floating point types and integer types can be used in the same expression, as long as the integer types are cast to floating point types using the cast function. For example,CAST ( num1 AS FLTP ) / CAST ( num2 AS FLTP )is a valid expression, where num1 and num2 are integer types.

The operator / is allowed only in floating point expressions, where both operands have the type FLTP or f. For example,num1 / num2is a valid expression, where num1 and num2 are floating point types. If the operator / is used in an integer expression or a decimal expression, a syntax error occurs.

Decimal types and integer types can be used in the same expression, as long as the expression is a decimal expression. A decimal expression has at least one operand with the type DEC, CURR, or QUAN or p with decimal places. For example,num1 + num2is a valid expression, where num1 is a decimal type and num2 is an integer type.

The operator ** is allowed only in floating point expressions, where both operands have the type FLTP or f. For example,num1 ** num2is a valid expression, where num1 and num2 are floating point types. If the operator ** is used in an integer expression or a decimal expression, a syntax error occurs.

The possible replacements for ''???'' in the CDS view entity definition with an input parameter are A. built-in ABAP type and C. A data element. These are the valid types that can be used to specify the data type of an input parameter in a CDS view entity. A built-in ABAP type is a predefined elementary type in the ABAP language, such as abap.char, abap.numc, abap.dec, etc. A data element is a reusable semantic element in the ABAP Dictionary that defines the technical attributes and the meaning of a field12. For example:

The following code snippet defines a CDS view entity with an input parameter currency of type abap.cuky, which is a built-in ABAP type for currency key:

Define view entity Z_CONVERT With parameters currency : abap.cuky as select from ... { ... }

The following code snippet defines a CDS view entity with an input parameter currency of type waers, which is a data element for currency key:

Define view entity Z_CONVERT With parameters currency : waers as select from ... { ... }

You cannot do any of the following:

B . A built-in ABAP Dictionary type: This is not a valid type for an input parameter in a CDS view entity. A built-in ABAP Dictionary type is a predefined elementary type in the ABAP Dictionary, such as CHAR, NUMC, DEC, etc. However, these types cannot be used directly in a CDS view entity definition. Instead, they have to be prefixed with abap. to form a built-in ABAP type, as explained above12.

D . A component of an ABAP Dictionary structure: This is not a valid type for an input parameter in a CDS view entity. A component of an ABAP Dictionary structure is a field that belongs to a structure type, which is a complex type that consists of multiple fields. However, an input parameter in a CDS view entity can only be typed with an elementary type, which is a simple type that has no internal structure12.

A metadata extension is a RESTful Application Programming object that can be used to organize the display of fields in an app. A metadata extension is a CDS view that annotates another CDS view with UI annotations, such as labels, icons, or facets. These annotations define how the data should be presented in the app, such as which fields should be shown on the object page, which fields should be editable, or which fields should be used for filtering or sorting.A metadata extension can also be used to add custom actions or validations to the app12.Reference:1:Refine the Object Page with Annotations | SAP Tutorials2:ABAP RAP : Enabling custom actions with a dialog for additional input fields | SAP Blogs
