    <p>My significant other uses Crystal Reports in the course of her duties, and has come to me for assistance. She has written a mapping function as shown below and is surprised that gets the fallout value when a client has multiple cards (see diagram). </p> <p><img src="https://i.stack.imgur.com/9yKfD.png" alt="diagram"></p> <p>In this model, when a client has a care visit, the client's card is supposed to be indicated in the client visit record for government reporting purposes. While the card id is not conceptually optional, it is quite possible that the card is not on file at the time the visit details are being logged, so their system allows this to be left temporarily unfilled. This state is represented by the "no card" condition in the mapping function below.</p> <p>Unsatisfied with my response that this means none of her conditions is met, she has asked me to post her appeal for help.</p> <p>Below is the Crystal Basic code from her mapping function. She is aware that there is an unhandled case in the last condition, and in that case a blank would be displayed, which is not the observed behaviour. The names from the diagram don't match the names in the mapping function code because the diagram is my synthesis of much arm-waving and explanation, whereas the code is pasted directly from the report and contains actual field names.</p> <pre><code>if ({awt_temp.Service_code} = "DOM") and ({Card_Type.Card_Type_ID} = 21) then {Card_Holder.Card_No} else if ({awt_temp.Service_code} = "MANT") and ({Card_Type.Card_Type_ID} = 25) then {Card_Holder.Card_No} else if ({awt_temp.Service_code} = "PC") and ({Card_Type.Card_Type_ID} = 22) then {Card_Holder.Card_No} else if ({awt_temp.Service_code} = "RES") and ({Card_Type.Card_Type_ID} = 24) then {Card_Holder.Card_No} else if ({awt_temp.Service_code} = "SOC") and ({Card_Type.Card_Type_ID} = 23) then {Card_Holder.Card_No} else if not ({Card_Type.Description} startswith "vhc") then "no card" </code></pre> <p>There is no point mentioning that the mapping function would best be handled with a join to a lookup table. She's not in a position to redesign the schema.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
