Diagnosis
When you executed a query, a runtime error occurred when converting acurrency amount or a quantity amount for a statistic or ranked list. Asa result, the system was unable to convert to the reference unit youspecified.
When converting currency amounts, the system assumes that the tableTCURR has the necessary entries. When converting quantity amounts, itassumes that the entries are the same size and that the tables T006...have the necessary entries.

System Response
At the end of your query report, you always see a list of anyconversion errors that have occurred. In statistics and ranked lists,the values where conversion errors occurred are displayed in reversevideo.
At the end of ranked lists, conversion errors are sometimes reported,even though no offending values are displayed in reverse video. In thiscase, the conversion error is the result of calculating a value on aline that is not actually displayed in the query list.

Procedure
The action you take depends on the type of conversion error:

• If the error occurred when converting currencies, ask your system
administrator to maintain the table TCURR.

• If the error occurred when converting quantities, you must first check
that the quantity units are the same size. If so, ask your systemadministrator to check the tables T006... . If the quantity units havedifferent dimensions, the statistic or ranked list you require cannotbe generated for the selections you have entered on the selectionscreen.
