ALV - Please help

[Former Member]

Hi All,

Please let me know the purpose of 'TECH' field ( fieldcatalog properties) in Reuse_alv_fieldcatalog_merge function module in SLIS

Thanks.

Hi,

If TECH field is set, the relevant field is not displayed on the list and cannot be shown interactively. The field is only known in the field catalog. (For example, it must not be specified as a sorting criterion).

reward points if it is helpful...

regards,

Omkar.

Hi,

Tech (technical field)

Value set: SPACE, 'X'

'X' = technical field

Field cannot be output in the list and cannot be displayed interactively. Field can only be used in the field catalog (not in IT_SORT, ...).

Hi

Reference to fields with currency/measurement unit

Each internal output table sum or quantity field whose decimal places are to be formatted appropriately for the unit in the list must follow the convention:

• the field is of data type QUAN or CURR (internal type P) (the field must really have this physical data type. Overwriting the physical data type with the parameter FIELDCAT-DATATYPE has no effect)

• There is a field in the internal output table which contains the associated unit.

• There is also an entry in the field catalog for the unit field.

(If the unit is not to appear as a column in the list, and cannot be interactively displayed as a column, e.g. because it is always unambiguous and is therefore explicitly output by the caller in the list header, the field catalog units field entry can take the parameter <b>FIELDCAT-TECH = 'X'.</b>

The association of a value field to a unit affects the output as follows:

• appropriate decimal places display for the unit

• an initialized field with a link to a non-initial unit is output as '0' for the unit (if FIELDCAT-NO_ZERO is initial). When this field is summed, this unit affects whether the units are homogeneous.

• an initialized field with a link to an initial unit is output as SPACE. When this field is summed, the unit SPACE does not affect the homogeneity of the units.

• When non-initial fields with an initial unit are summed, the unit SPACE is considered to be a unit.

Link to currency unit

• cfieldname (currency unit field name)

value set: SPACE, output table field name

Only relevant for amount columns with associated unit.

Name of the internal output table field containing the currency unit associated with the amount field FIELDCAT-FIELDNAME. The field in FIELDCAT-CFIELDNAME must have its own field catalog entry.

• ctabname (internal currency unit field output table)

value set: SPACE, output table field name

only relevant for hierarchical-sequential lists

Name of the internal output table containing the FIELDCAT-CFIELDNAME field.
